Product Name: Honeywell System 57 Calibration Plug (05701-A-0550)

Product Description: This is a specialized tool designed for calibrating gas sensors connected to the Honeywell System 57 gas detector controller. It’s not a functional module within a Distributed Control System (DCS) or Programmable Logic Controller (PLC) system itself.

Product Parameters & Specifications: In-depth details are scarce online, but based on its function, we can infer some characteristics:

It likely connects to a designated port on the System 57 controller to initiate a calibration routine for the connected gas sensors.
It might be a physical plug that bridges electrical connections to activate the calibration mode within the controller.
There could potentially be a configuration element to the calibration plug, but this is uncertain.
