The 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.
The real time status of each active sensor is displayed on a backlit LCD Touch Screen that also serves as a user interface. Display formats include field device function, tag name, current reading and alarm status. Each input can be configured for up to 3 alarm levels. A fourth alarm output is dedicated to fault diagnostics of field devices and internal operating systems. Each system application can include either common and or a limited number of discrete alarm relays. Model MCX-32 accepts Type I or Type II compact flash cards for data logging. Alarms, calibrations, comm errors and faults are logged. Hourly peak and average readings for each channel is also logged. Other features include one-touch Alarm Inhibit, Alarm Reset, and Alarm Silence (Acknowledge) functions. The MCX-32 includes a 10/100 BaseT Ethernet Port. This allows users to remotely monitor the MCX-32 from a desktop PC or handheld device with an Internet connection. An addressable RS-485 Modbus RTU slave port is available for communication with higher level automation and control systems such as PLC’s, PC’s and Distributed Control Systems.
The MCX-32 is available in 4 enclosure options – Model MCX-32-N1P NEMA 1 panel mount, MCX-32-N1R NEMA 1 rack mount, MCX-32-N4X NEMA 4X epoxy fiberglass, and MCX-32-SS NEMA 4X 316 Stainless Steel. The control system can be powered by 110-230 VAC or 24 VDC. MCX-32 Integrated Control Systems are intended for installation inside buildings or under cover avoiding direct sunlight.
