SignalFire Wireless Telemetry has expanded the capabilities of its Multi Input/Output (MIO) Module to connect directly (Modbus) with programmable logic controllers (PLCs) or be configured to perform autonomous local control where an input can trigger a relay output when a set threshold is met.
In its standard configuration, the MIO Module provides wireless I/O capability as part of Signal Fire’s Remote Sensing System, sending data from attached sensors to a SignalFire Gateway that can report inputs and write outputs via its wireless network.
Now, when operating in non-wireless Modbus mode, the SignalFire Multi I/O Module can be connected directly to a user’s controller via Modbus RS-485 or operate independently without any outside device controlling it. (see graphic 2) For example, when connected to analog level sensors, the MIO Module can locally create a command to shut off the pump if configured levels get too high. Additionally, the module can be connected wirelessly (or wired) to a monitoring device (PLC) to monitor status.
With 8 analog and 6 digital inputs (the DI’s can totalize), the Multi I/O Module can be connected to a variety of devices such as pressure, flow, or level sensors, motor controllers or radar sensors. Two relay outputs are offered for control. Units can be daisy chained for added flexibility. Ultra-low power design supports long-term operation using solar power. Units are certified to Class 1 Division 2, Temp Code T4, Groups C&D, CSA C22.2 No. 213, UL 61010-1, and CSA C22.2#61010-1 for operation in harsh conditions and challenging terrains.
