Flexible modular I/O

WEMS offers a range of modular I/O offers that deliver unprecedented flexibility, to simplify installation and minimise the cost of the overall installation.

Modular description

Our range of modular I/O offers unprecedented flexibility, to simplify installation and minimise overall installed project cost.

Consisting of a series of DIN rail mounted ‘modules’ that plug together, the various module types are each dedicated to one I/O function: digital inputs, thermistor inputs, analogue inputs, analogue outputs and relay outputs, so you can select exactly the combination of points you need at each location, providing you with excellent flexibility and fewer wasted inputs/outputs.

Control & relays

WEMS MX Modular Controller

Controller

Our Controller module manages the I/O modules directly connected to it and provides power to all the modules. It requires a 12Vdc supply. The Controller has remotely upgradeable firmware and LED status indication.

WEMS MX Modular 5A Relay

Relay 5A

Our relay module provides a mains rated 230V relay output with a single pole changeover contact (Form C). The module also incorporates a manual override button along with LED status indication.

Analogue modules

WEMS MX Modular Analogue Input 0-10V

Analogue input 0-10V

This WEMS module provides two analogue inputs for devices with industry standard 0-10V outputs, such as air quality, CO2, pressure sensors etc.

WEMS MX Modular Analogue Loop 4-20mA

Analogue loop 4-20mA

The analogue loop provides two analogue inputs for devices with industry standard 4-20mA current loop outputs such as temperature, humidity, CO2 or pressure sensors etc. This module has the capability of providing a 24VDC instrument supply to power the sensing device.

WEMS MX Modular Thermistor

Themistor (10K)

This thermistor module provides four inputs to monitor 10K3A1 thermistor temperature sensors.

Digital modules

WEMS MX Modular Digital Input

Digital input (48V)

The digital input module provides four optically isolated inputs for status and alarm monitoring or meter pulse counting. Maximum pulse count frequency is 10Hz. LEDs provide status indication for each channel. Inputs require (wetting) voltage of 12 – 48V dc.

Communications modules

WEMS MX Modular 434MHz Wireless Module

434MHz wireless

This comms module provides 434MHz wireless connectivity to the module cluster, and supports hopping to extend the network range. 434MHz offers the best range characteristics and is permitted for use in the European markets and some other countries (including the USA).

WEMS MX Modular 868MHz Wireless Module

868MHz wireless

The 868MHz module provides wireless connectivity to the module cluster, and supports hopping to extend the network range. Use of this frequency is permitted in the European markets and some other countries. There is the option to amplify the signal to achieve up to 2.5km range.

WEMS MX Modular 915MHz Wireless Module

915MHz wireless

Our 915MHz module provides wireless connectivity to the module cluster, and supports hopping to extend the network range. Use of this frequency is permitted in the North American markets.

WEMS MX Modular RS485 Module

RS485

Provides RS485 communications module provides connectivity via twisted-pair cable (Belden 9841). This is typically used for connecting RS485/Modbus enabled equipment.
