Input/Output Circuits
The MPRR’s two RF sense input circuits are designed to connect to dry contact clo-
sures. The MPRR’s tag lock output circuit is a single-pole, double-throw relay provid-
ing a dry contact closure. These contacts are rated at 42.2V AC peak (30V
sures. The MPRR’s tag lock output circuit is a single-pole, double-throw relay provid-
ing a dry contact closure. These contacts are rated at 42.2V AC peak (30V
rms
) or 60V
DC, at 1 A maximum with noninductive load.
