ProVu Expansion Modules

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 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.

The PDA1485 converts the serial output of the ProVu meter to balanced, full or half-duplex RS-485 signals. The PDA1485 has a removable screw terminal connector for the RS-485 terminals which includes Transmit Data (DO) and (/DO), Receive Data (DI) and (/DI), and Signal Ground. The adapter is provided by the ProVu meter M-Link connection. The PDA1485 has three diagnostic LEDs: a Power (P) LED to show when the adapter is powered properly, a Transmit Data (TX) LED to show when the adapter is sending data out from the PC side, and a Receive Data (RX) LED to show when the adapter is receiving data from the ProVu meter.
