MTL4728+ FOR FOUR OUTPUTS digital (on/off) or 4/20mA controller outputs.

The MTL4728+ is a 4-channel barrier designed primarily for controller outputs and for solenoid, alarm and LED driving applications. As each loop is powered, typically, by a single channel, the module can drive four hazardous-area devices. It is not designed to accept bussed power since, for solenoid driving applications, the control switch is often in the power leg of the circuit. The unit incorporates an earth return circuit (as opposed to the MTL4787+ and MTL4787P+ modules which cover a similar range of applications but with a diode return)
