Model MCX32

Detcon Model MCX-32 is a multi-channel integrated control system with a capacity of 64 active channels.

It can receive and supervise inputs from a wide range of field devices with either a 4-20mA DC or serial output. The standard serial protocol is RS-485 Modbus RTU.

This unique system design features “auto-configuration” of addressable devices that are located in a device library.

The Model MCX-32 controller provides a unique combination of “auto configuration” simplicity and ease of use with customizable expansion capabilities.

The Model MCX-32 controller features a flexible design that allows the user to customize a system by choosing from a selection of individually addressable field devices or use addressable input and output modules.

Detcon’s full range of gas sensors (purchased separately) can be used to create a gas detection system consisting of toxic gas, combustible gas, and/or oxygen deficiency.

A wide range of field devices such as liquid level, temperature, pressure, flow, etc., can also be configured for input to the control system.

Four standard I/O modules are available: a 4-channel 4-20mA input module (DA-4), a 4-alarm relay output module (RL-4), a 4-channel 4-20mA output module (AO-4), and a 4-relay contact input module (DI-4).

I/O modules are din-rail mounted and stackable allowing for seamless system expansion.

The I/O modules may be mounted within the main system enclosure or in separate enclosures suitable for the area classification where installation will occur.

In many cases using distributed I/O nodes can significantly reduce wiring and installation costs...
