The PDA1004 four relay external expansion module adds four 3 amp Form A (SPST) relays to any ProVu meter. It can be configured for functions similar to the ProVu onboard relays and can be added at any time.
The PDA1011 analog output external expansion module adds an additional two (2) analog outputs to any dual-input ProVu meter or ProVu Modbus® scanner (i.e. PD6060, PD6080, PD6081, PD6088, PD6089, PD6262, PD6363, or PD6400). It can be configured for functions similar to the ProVu onboard analog output and may be added at any time.
The PDA1044 digital I/O external expansion module adds four digital inputs and four digital outputs to any ProVu meter. Up to two digital I/O expansion modules may be added to each meter, for a total of eight (8) additional digital inputs and outputs per meter.
External digital inputs function similarly to the F4 digital input on most ProVu models. They can be configured to trigger events (e.g. acknowledge/reset alarms, reset max and/or min values, disable/enable all output relays), provide specific menu access, or mimic front keys.
Digital outputs can be used to remotely monitor alarm relay states or the states of a variety of actions and functions executed by the meter.
