OVERVIEW
• 24 field configurable input ranges
• DC Voltage Input: 0-50 mV to +/- 10 V
• DC Current Input: 0-1 mA to 0-20 mA
• Output: (2) DPDT Relays - One Alarm Setpoint
• Field-Configurable by User
The APD 1080 accepts a DC voltage or current input and provides visual alarm indication and alarm relay contact outputs. 15 voltage and 9 current input ranges can be field-configured via external rotary and slide switches. Offset ranges such as 1-5 VDC and 4-20 mADC are also included.
Heavy-duty relay contacts allow the module to directly control high capacity loads. Front-accessible potentiometers are used to adjust the alarm setpoint from 0 to 100% and the deadband from 1 to 100%.
The APD 1080 provides a single setpoint adjustment of the two DPST relay contacts. The alarm output can be field configured for HI or LO operation, latching or non-latching, and normal or reverse acting.
All models are field configurable
