l WC25i Single Endpoint configuration- The two Digital Inputs

areread and forwarded to the Gateway at the interval selected in the Checkin Interval list box in the Device Configuration

window (on page 52).

l Each input is totalized and the frequency is reported. l If the State Change Checkin list box selection is Yes

(enabled), all readings (analog and digital) are sent to the WC45i-Gateway immediately.

Caution: Do not enable the State Change Checkin list box for rapidly changing inputs.

l WC25i System configuration - Whenever Digital Input 1 or

Digital Input 2 is closed on one of the WC25is, Relay 1 or Relay 2 is energized on the other WC25i.

11 Analog Inputs

Note: See Analog Inputs (on page 15) to designate the WC25i as either mA or Volts.

l WC25i Single Endpoint configuration- The four Analog Inputs

(AIN1-AIN4) on the Endpoint are read and forwarded to the Gateway at the interval selected in the Checkin Interval list box in the Device Configuration window (on page 52).

l WC25i System configuration - The four Analog Inputs (AIN1-

AIN4) on the Endpoint aremirrored wirelessly to the four Analog Outputs (AO1-AO4) on each WC25i.

12 Analog Outputs

Note: See Analog Outputs (onpage 15) to designate the WC25i as either mA or Volts.

l WC25i Single Endpoint configuration- The four Analog

Outputs (AO1-AO4) on the Endpoint are controlled using Modbus write commands from the master Modbus device connected to the Gateway.

l The Analog Outputs are always written in μA even when the

switch is set for a 1-5V output.

l It is up to the PLC to convert the readings to voltage.

l WC25i System configuration - The four Analog Inputs (AIN1-

AIN4) on the Endpoint aremirrored wirelessly to the four Analog Outputs (AO1-AO4) on each WC25i.

3.1.1. Digital Inputs

The two Digital Inputs (DIN 1 and DIN 2) can be dry contact or voltage (must be push-pull with 30 Volts maximum).

Important!: Verify the connection to the ground bus from the moduleis to either the groundof the

voltage device or the dry contact.

3.1.2. Relay 1 Outputs (Digital)

There are two relay outputs:

l Relay 1 Output is a DPDT l Relay 2 Output is an SPDT. l These relays are rated for:

l 30 VDC @ 2 Amps l 250 VAC @ 0.25 Amps

3.1.3. Analog Outputs

In (Figure 3), each switch controls the output mode for a pair of outputs.

l The switch on the left sets both Output 1 (AO1) and Output 2 (AO2) to either mA or Volts. l The switch on the right sets both Output 3 (AO3) and Output 4 (AO4) to either mA or Volts. l In mA output mode, the compliance voltage is the Endpoint supply voltage.

3.1.4. Analog Inputs

The Analog Inputs may operate in either Current (0-20mA / 4-20mA) or Voltage (0-5V / 1-5V). The input mode is set usingslide switches inside the WC25i (Figure 3).

Figure 3: WC25i Switches

1. Use the Small, flathead screwdriver to remove the cover of the WC25i.

The cover is held on by clips.

2. Slide the switch corresponding to the input channel to:

l Volts for a Voltage Input. l mA for a Current Input.

3. Wire the analog voltage or current to the set of screw terminal connections.

4. Replacethe WC25i cover.

Caution: Maximum input voltage (for eitherCurrent or Voltageinput mode) is 10 Volts. The compliance voltage for a 4-20mA device must be provided externally. See the Example: Analog Inputs Wiring Diagram (on page 16) for details.
