External Wiring Recommendation
The following information pertains to the wiring diagram above.
Output Section 2 Channels
Input Section 4 Channels
1. Jumpers are required between IN (+) and SENSE terminals for all current input
ranges.
2. Pins 1 ... 20 are outputs.
Pins 21 ... 40 are inputs.
3. Use shielded signal cable. In noisy environnements, twisted shielded cable is
recommended.
4. Shielded cables should be connected to the PLC’s ground.
5. A Shield Bar (STB XSP 3000 and STB XSP 3010/3020) should be used to
connect the shielded cable to ground (see page 726).
6. For Inputs, the maximum channel to channel working voltage cannot exceed
30 Vdc.
7. N / C = Not Connected.
NOTE: V is an optional voltmeter that can connected to read voltage that is
proportional to the current. Wiring to this terminal must not exceed 1 m.
Diagnostic
To prevent improper fault indications, unused inputs should have the + (plus) and -
(minus) inputs tied together and be configured for a bipolar input range.
Typical Wiring Outputs
Channel 1 The output shows a connection to an external field device
and optional monitor.
Channel 2 The output shows a connection to an external field device
and the input of channel 1.
Typical Wiring Inputs
Channel 1 Channel 1 shows 4 - 20 mA current input controlled by
output section Channel 2.
Channel 4 The input shows a connection to a voltage output sensor.
