Installation Form: Standard DIN rail snap-in installation

Compatible Systems: Tricon full series V9/V10/V11 systems

Replacement Relationship: The same function 9760-210 is a 32-channel version, this product is a 16-channel simplified version

Panel Indicator Lights

CH Channel Green Light: Normal analog signal input for the corresponding circuit

FAULT Red Light: Circuit short circuit, open circuit, or signal beyond range fault alarm

II. Operating Instructions

Installation Location

Internal signal side rail installation in the cabinet, close to the field instrument, 32-point analog module requires two 9761-210 to be used together.

Installation Procedure

Directly insert into 35mm standard rail for fixation, after wiring, connect the dedicated flat cable, supports hot-swappable replacement without downtime.

Wiring Specifications

Compatible with two-wire and three-wire 4-20mA transmitters, use shielded twisted pair wiring, single-ended grounding of the shielding layer, built-in sampling resistor does not require external conversion resistor. Operating status

Normal operation: The green light of the corresponding channel lights up when the signal is normal. The fault indicator light remains off. The signal is stable and free from interference.

Fault handling

If the fault indicator light comes on, the priority is to check the power supply of the instrument, the connection of the lines, and the looseness of the wiring. After confirming that there are no errors in the external lines, the terminal board can be replaced.
