Terminals Description
TB1-1, TB1-2, TB1-3
TB1-4, TB1-5, TB1-6
Terminals TB1-1, 2, 3 are designated to Analog Input 1 and TB1-4, 5, 6 are designated to Analog Input 2. These can be
connected to a customer device which sends signals between ±10V. The analog voltage supplied is sampled by a 14-bit
analog-to-digital converter, and the resulting value is stored in parameter P36 (A/D Converter 0 Input). The internal circuitry
has an 80k differential input resistance and a 40k common-mode input resistance. 14AWG wiring is recommended for
customer connection.
TB1-7, TB1-8
TB1-9, TB1-10
Terminals TB1-7 and TB1-8 supply analog output from parameter P47 (D/A Converter 1 Output); TB1-9 and TB1-10 supply
analog output from parameter P48 (D/A Converter 2 Output). The RGU can be programmed to report parameter values (such
as trend parameters) to the customer device. The customer device must have a minimum 1k load resistance. 14AWG
wiring is recommended for customer connection.
