- Accepts transmitter, self-powered current and supervised contact inputs
- Separates sixteen channels into two group-isolated banks of eight
- Requires the correct termination assembly, Type 4 cable and loop-power method
FBM211 RH914TN is a Foxboro FBM211 0 to 20 mA input module designed for supported Foxboro DCS 200 Series baseplates.
It converts sixteen field inputs into controller values over the redundant module Fieldbus while supporting transmitter loops, self-powered sources and supervised contacts in two group-isolated banks.
Before installation or replacement, verify processor and software support, baseplate position, termination assembly, Type 4 cable, loop-power method and the saved channel database.
Availability, condition, price, and shipping time for FBM211 RH914TN are confirmed during quotation.

- Configure each channel for the actual transmitter or supervised contact circuit
- Preserve conversion-time, rate-of-change and engineering-unit settings
- Add the documented 200 Ω series assembly when a FoxCom or HART transmitter requires it
- Use RH916JT for customer-supplied external loop power
- Use RH916BT for FBM auxiliary +24 VDC loop power
- Connect the selected TA through the documented Type 4 termination cable
- Use front LEDs and controller diagnostics to separate module and field faults
- Investigate shared reference or field-power problems when eight channels are affected
- Verify communication over both A and B Module Fieldbus paths before removing maintenance bypasses
- 2-wire 4 to 20 mA process transmitter acquisition
- Self-powered 20 mA analog source measurement
- Line-monitored dry-contact input using end-of-line resistors
