NOTES:
1. The terminals accept 14-26AWG wire, and the screws shall be torqued to 0.4-0.5Nm (3.5 – 4.4
in-lb)
2. Any combination of sensor type inputs is allowed
3. Shielded cable is required for EMC conformity and is recommended for all remote sensor
installations. The shield shall be grounded at the transmitter end only. If the shield is grounded at
the remote end, the shield shall not be connected at the transmitter end.
4. When remote mounted probe sensors are used, and the shield is grounded at the probe, the
shield shall not be connected at the transmitter end.
5. Duplex (redundant) sensors that are bonded to the probe are not permitted. All
thermocouple/mV, RTD/ohms, and HLAI inputs must be isolated from ground (the probe) and
from each other.
6. Digital Input switches, DI, must be dry contact type, simple apparatus and properly segregated
from all other sources of power.
