The RM4-TR is a DIN rail mounted instrument used for counting, rate
measurement, totalising and offering programmable grand total functions as
well. The RM4-TR takes pulse input and can be configured for a very wide
range of pulse types - from contact closure to PNP and NPN transistor to
square wave. The programming is very flexible making the RM4-TR ideal for
most applications involved in counting, rate and total. The RM4-FX offers ratemeter/tachometer functions.
All RM4 instruments have a 5 digit LED display and 2 setpoint relays as standard.
