Intelligent PM4 Monitors

PM4

(Amalgamated Instruments)

Applications:

Signal Conditioning and Displays

The instruments feature flexible pushbutton calibration and programming to suit most applications. Each instrument is supplied with a single control/alarm relay as standard.

A transmitter supply is provided as standard on AC supply models (18VDC regulated). Optional outputs include additional relays, isolated analog output (single or dual channel, single channel configurable as retransmission or PI control), serial (RS232 or RS485) communications. Relays can be configured for alarm, trailing or PI control (time division or frequency) operation. The programmable digital filter improves stability by smoothing out short term interference. An external input is configurable to perform one of various functions e.g. Two level brightness switching, peak hold, display.
