2 About the Modules
Input Modules
For input modules, DC inputs are 24V DC nominal, with an input range of 10…28.8V dc, and are offered with 2, 4,or 8 sinking style inputs, or 2, 4, or 8 sourcing style inputs. The 1734-IB2, 1734-IB4, 1734-IB4D, and 1734-IB8 input modules are sinking modules. The 1734-IV2, 1734-IV4, and 1734-IV8 modules are sourcing input modules.
For input modules, AC inputs are 120V AC nominal with an input range of 85…132V ac, or 220V AC nominal with an input range of 159…264V ac, with sinking inputs.
Features of the all input modules include the following:
Autobaud (will match baud of existing devices on the network)
Selectable input filter times (0…65 ms with 1 ms default)
Sequential auto addressing
Output Modules
The 1734-OB2, 1734-OB4, 1734-OB8, 1734-OB2E, 1734-OB4E, and 1734-
OB8E DC output modules have current limited sourcing outputs, which source a positive voltage of up to 1 A with respect to their DC return per channel. The 1734-OB2EP sources a positive voltage of up to 2 A with respect to its DC return per channel. The outputs are not isolated from each other. For these modules, DC outputs are 24V DC nominal, with a range of 10…28.8V dc. A number of output diagnostic features are incorporated to assist in troubleshooting. The 1734-OB2E, 1734-OB2EP, 1734-OB4E, and 1734-OB8E modules feature the following:
Output diagnostics (short circuit and wire-off indication and reporting
bits per channel)
Current limited outputs

The 1734-OA2 and 1734-OA4 AC output modules have sourcing outputs,
which source a voltage of up to 0.75 A per channel. The outputs are not isolated from each other. For this module, AC outputs are 120/220V AC nominal, with a range of 74…264V dc. The 1734-OA2 and 1734-OA4 modules feature the following:
Autobaud (will match baud of existing devices on the network)
Sequential auto addressing
Relay Output Modules
Two versions of relay modules are:
1734-OW2, 1734-OW4 relay module.
1734-OX2 relay module.
The 1734-OW2 and 1734-OW4 relay outputs are Type A (Normally Open), the 1734-OX2 relay outputs are Type 2 Form C. Both modules’ outputs sink or source a current with respect to power or return. Contact outputs are isolated from each other. Each output is rated 5…240V rms at 2 A (current is load dependant). Features include:
Autobaud (will match baud of existing devices on the network).
Sequential auto addressing.

Analog Modules

The 1734 analog modules consist of input modules (1734-IE2C and 1734­IE2V) and output modules (1734-OE2C and 1734-OE2V). Each module has two single-ended, non-isolated channels.
Cat. No. Module Type Number of
Channels
1734-IE2C Analog Input 2 16 bits across 0…21 mA 1734-IE2V Analog Input 2 15 bits plus sign across -10…10V 1734-OE2C Analog Output 2 13 bits across 0…21 mA 1734-OE2V Analog Output 2 14 bits across -10…10V
Resolution
The features of the analog modules depend on the type of analog module: input or output. These are features common to both input and output modules.
Data - The current input and output modules operate in unipolar mode
only. Voltage input and output modules operate in unipolar or bipolar modes. Data returned from the module is scaled by the user to any 16 bit signed integer (–32,768...+32,767).

(1) Supply voltage can range from +5V DC… 240V AC, depending on relay load.
12/24V DC power for the module is provided by the external power supply. The power supply voltage may be daisychained from a 1734 adapter, 1734-FPD module, or 1734-EP24DC power supply communication interface. Each channel is individually isolated and may have a unique supply or voltage as necessary.
ATTENTION: Do not attempt to increase load current or wattage capability beyond the maximum rating by connecting two or more outputs in parallel. The slightest variation in relay switching time may cause one relay to momentarily switch the total load current.
Make certain that all relay wiring is properly connected before applying any power to the module.
Total current draw through the wiring base unit is limited to 10 A. Separate power connections to the terminal base unit may be necessary.
Use the end cap from your adapter or interface module to cover the exposed interconnections on the last mounting base on the DIN rail. Failure to do so could result in equipment damage or injury from electric shock.

Outputs are electronically protected to 0.75 A. Module outputs are selectable for latched mode or auto-reset mode. (Latched/auto reset is set by module, not by individual channel.) Each channel is assigned a bit in the data table to indicate the faulted condition. Outputs in the latched mode can only be reset with a user command to the module.
