Serial indicator with Modbus

Serial input indicator, Instrotech IQ230
Model IQ230 
is a 6-digit panel-mount serial input remote indicator for RS232 and RS485.

Serial communications is supplied as standard with MODBUS™ RTU and MODBUS™ ASCII protocols.  A simple ASCII-out protocol is also provided for serial printing, datalogging and large display interfacing.

Advanced features include max/min recording; programmable front pushbuttons; 2 programmable digital inputs; security menu lockout; and built-in menu help hints.

The alphanumeric high-bright LED display and programming help prompts makes for quick and easy set-up.  Model IQ230 options include up to 4 relays, analogue retransmission, and real time clock for date and time stamping.
