HC320
Features
Application
HC320 is generally used for the supervision of m A signals. The signal may be delivered by a standard sensor with 4-20 m A output or from one of our HCxxx transmitters. The HCxxx familiy consists of transmitters for p H, O2, conductivity and temperature etc. Power consumption may be supervised using the HC320 with one of our APM modules.
Analogue input The analogue input is a current input, and may be set up to either 020m A or 4-20m A. Futhermore, the input may be scaled to display 100% down to 10m A. Digital input The HC320 may be configured to both positive and negative logic on the digital inputs. Using parameter no. 10 the input may be set to either active high og active low. With positiv logic the accepted input voltage range is 5-30Vdc. Negative logic is achieved by connecting the input to Gnd
- i.e. by using a swicth. Relay output
The unit contains two relays
- one for each limit. The relays are both connection relays, but the polarity may independently be...
