The ezTCP SIG-5450 from Sollae Systems is a remote I/O gateway equipped with 2 digital output ports connected to relays and an Ethernet interface. The device is designed to control the equipment from remote control centers or HMI devices via Modbus TCP protocol. The device can also be controlled by using any Modbus TCP software/app.

We provide free software and a smartphone app, called ModMap, which lets you manage multiple devices easily and conveniently.

Apart from ON/OFF control, each individual digital output can generate a pulse when receiving a specific Modbus TCP request from a remote device, software, or smartphone app.

The relays connected to digital output support both NO (Normal Open) and NC (Normal Closed) mode. The SIG-5450 supports up to four TCP connections simultaneously, enabling to monitor sensors from different HMI/software/apps at the same time.
