SignalFire Class I, Div. 2 certification for wireless I/O, gateways

The Modbus DIN mount gateways and wireless I/O modules now are certified to Class I, Div. 2 standards, allowing their use as part of remote monitoring and control systems in harsh environments with the occurrence of explosive gases. The gateway serves as a two-way interface between remote transceiver nodes that interface with a variety of sensors and a PLC, connecting asset managers to a remote mesh network of assets using an industry-standard Modbus protocol. The wireless I/O module serves as a wire replacement by replicating analog and digital signals (discrete, 4-20 mA and 1-5 V) with another module through a wireless link.
