INTRODUCTION
1.1 GENERAL INTRODUCTION
The Low Power I/O Expansion Board (LPI/OEB) measures approximately 4” by 7.25” and
mounts piggy-back on either the TeleFlow or TeleRTU CPU Board. Removable card-edge
connectors are provided to accommodate field wiring. A 1.25” by 1.2” cutout area is incorporated into the board’s design to accommodate mounting of the Multivariable Transducer’s Wet End Connector and Balance Board onto the TeleFlow CPU Board. The
LPI/OEB operates in conjunction with Revision 3 and higher TeleFlow CPU Boards and
with TeleRTU CPU Boards. Three versions of the LPI/OEB are available; fully populated
version P/N 392927-01-2 (see Figure 1), depopulated version that supports DI/DO and the
Comm. Port P/N 392927-02-0 and a depopulated version that supports DI/DO only P/N
392927-03-9.
Figure 1 - Low Power I/O Expansion Board
PIP-EXPI/OTF Page 1 Low Power I/O Expansion Board
The Low Power I/O Expansion Board provides the following additional I/O capabilities to
the TeleFlow Plus EGMCs, TeleRTU Plus and TeleRTU Module RTUs and TeleRecorders:
• 8 Discrete I/O
All eight DI/O function in both input and output capacities. Field terminals for each
DI/O are I/O and GND. Each Discrete Input will accept signals from 0 to 16 VDC. The
Discrete Outputs utilize open drain FETs with a maximum working voltage of 16 VDC
and a minimum load of 100 mA. DI/Os are not isolated.
• 4 Analog Inputs (available on 392927-01-2 only)
Two single-ended Analog Inputs are available for 4 to 20 mA or 1 to 5 VDC signal
operation (Jumper Configurable) and two additional single-ended Analog Inputs are
available for 1 to 5 VDC signal operation only. The two 4-20 mA Inputs will support
externally powered transmitters; however, internally powered 4-20 mA transmitters
will require an external power supply. All four channels support low power voltage
output transmitters such as Rosemount and Honeywell. Resolution is 12 bits (1.42
mV) and combined error (including linearity, hysteresis and temperature effects) is ≤ ±0.2%. Each Analog Input channel includes field wiring terminals for signal,
transmitter power (+9.5V), and ground. Note: Analog Inputs are designated AI5
through AI8; AI1 through AI4 are assigned to the TeleRTU CPU.
• 1 Analog Output (available on 392927-01-2 only)
The Analog Output can be configured for 4 to 20 mA or 1 to 5 VDC operation (Jumper
Configurable). Resolution is 12 bits and combined error including linearity, hysteresis
and temperature effects is ≤ ±0.2% after calibration.
• 1 High Speed Counter Input (available on 392927-01-2 only)
The High Speed Counter input will accept pulses (with an input range from 0 to 16
VDC and up to 10KHz) from CMOS or TTL sources, including transistors, FETs,
mechanical relays, or other signaling devices.
• 1 RS-232 or RS-485 Asynchronous Serial Communications Port (not on 392927-03-9)
Note: Only supported by units with TeleFlow/ACCOL Firmware

2.2 I/O CONFIGURATION & WIRING
Figure 4 - LPI/OEB Discrete Input Configuration
2.2.1 LPI/OEB Discrete Input Wiring (TB4) (see Figure 4 and Table 4)
Discrete Inputs have a range of 0-16 Vdc ±10% and have surge suppression but are not
isolated. A Discrete Input is activated by closing the connection between DI/On and Ground
(GND) with a Dry Contact (such as a transistor, mechanical relay, TTL, CMOS and other
devices which provide from 0-16 Vdc). The Discrete Input (DI) is lightly pulled up to 5V.
2.2.2 LPI/OEBDiscrete Output Wiring (TB4) (see Figure 5 and Table 4)
Each Discrete Output is wired to an open drain capable of switching up to +16 Vdc at
100mA. Surge suppression is provided via 16V bi-directional Transorbs across each out-put;
however, since these outputs are not isolated, caution must be exercised to ensure that the
load current does not adversely affect operation of the TeleFlow Plus or related devices.
2.2.3 LPI/OEB Analog Input Wiring (TB2) (see Figures 6 through 8 and Table 5)
Up to 4 single ended analog inputs can be wired to the I/O Expansion Board. Analog Inputs
5 and 6 can be configured as 1-5 V non-isolated inputs, 4-20 mA non-isolated inputs, or 4-20
mA loops powered internally and referenced to the board’s analog ground (AGND). When
configured for internally powered current loop operation (which can be turned off when the
CPU Board is in SLEEP mode), an external 21V power supply is required. Analog Inputs 7
and 8 can only be configured for 1-5 V non-isolated input operation

2.2.4 LPI/OEB Analog Output Wiring (TB3) (see Figure 9 and Table 1)
Figure 9 - LPI/OEB Analog Output Configuration
Low Power I/O Expansion Board Page 12 PIP-EXPI/OTF
The single analog output can be configured for 4 to 20 mA or 1 to 5 V operation. The analog
output section of the LPI/OEB consists of a bus interface, a one channel Digital to Analog
Converter (DAC) and signal conditioning circuitry designed to generate a 4-20 mA output or
a 1-5 V output. Jumper JP19 controls selection. When set in position 1-2, JP19 configures
the analog output for current loop operation. When set in position 2-3, Jumper JP19
configures the analog output for 1 to 5 V operation.
2.2.5 LPI/OEB High Speed Counter Wiring (TB3) (see Figure 10 & Table 1)
The High Speed Counter input circuitry is powered from the 5V power source on the
LPI/OEB. The HSC Input is configured as a dry contact input with filtering and surge
protection. Field connections are HSC and GND. The frequency range of the HSC is DC to
10KHz. Field devices can be open collector transistors, open drain FETs or dry contacts.
Figure 10 - LPI/OEB High Speed Counter Configuration
2.3 RS-232/RS-485 COMMUNICATIONS
Terminal Block TB5 can be configured to support RS-232 or RS-485 communications (see
Figure 11).
For RS-232 operation the following configuration jumpers must be set:
JP13 Jumper to JP16
JP22 Pin-1 to Pin-2 for RTS to CTS Loopback or Pin-2 to Pin-3 for use with an external
CTS
For RS-485 operation the following configuration jumpers must be set:
JP14 Jumper to JP16
JP15 - 120 Ohm TX Termination (at end nodes ONLY)
JP17 - 120 Ohm RX Termination (at end nodes ONLY)
JP20 - RX Pull-up (Install at end node with RX Term. Installed)
