SCM7B

SCM7BP01/SCM7BP02

Backpanel

Description

The SCM7BP01 (Figure 3) and SCM7BP02 (Figure 4) are 1 and 2 channel

backpanels. Unlike other backpanels available, both the system and field side

sides have screw terminal connectors able to accept discrete wire (10-24 AWG).

The backpanels can be ordered with standoffs to allow mounting, using a #6

or smaller screw, or with DIN rail mounting hardware.

System Side - Power

Both backpanels accept 14-35VDC between V+ and COM using a screw

terminal (10-24 AWG) block. No reverse supply diodes are provided with this

model, but both are fused at 1/4 Amp (01) or 1/2 Amp (02) for module protection.

Field Side - Signal

On the field side, a temperature sensor is mounted underneath the field side

terminal block to provide cold junction compensation for thermocouple modules,

and a current-to-voltage conversion resistor (P/N SCM7BXR1) socket location

is provided (supplied with SCM7B33 modules).
