FEATURES
Application HC320 is generally used for the supervision of mA signals. 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 020mA or 4-20mA. Futhermore, the input may be scaled to display 100% down to 10mA. 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 inverted using parameters no. 7 and no. 8. Alarms are reset by either pressing the ‘Mode’ key or by activating the external reset input, S1. Limits The HC320 integrates two limits. All settings for one limit may be altered independently of the other.
