Convenient terminations are the features of the Panel-Mount 1781-5B08S and the DIN-Rail Mount 1782-5B08S. These mounting boards can accept 8 of the WRC 1781-5B or compatible analog modules in any mixture. A temperature sensor is mounted on each channel to provide cold junction compensation for thermocouple modules. Both the Field and Logic Connections are terminated with screw terminals. The 1781-5B08S and 1782-5B08S mounting boards are fuse protected through F1. A zener diode DZ1 provides extra protection by clamping the input power voltage to 5.6 V. If the input supply voltage connection is reversed, the zener diode will be forward biased and fuse F1 will be blown.
