[DISPLAY_ULTIMATE_PLUS]

The APM765 Panel Meter displays data collected from process current, DC voltage and temperature inputs. Several output options convert the display into a transmitter with proportional 4-20mA output or a serial communication interface. A relay output option adds limit alarm and pump control capabilities.

Process inputs can be scaled with or without applying an input for virtually any engineering units. Temperature inputs can be programmed to display in degrees Fahrenheit or Celsius.

Inputs
4-20mA DC, ±20mA DC, ±10V DC
Type J, K, T, E thermocouples
100 ohm platinum RTDs

Outputs (optional)
4-20mA (sink/source)
Dual SPDT (Form C) 3A relays
RS-232, RS-422/485 serial communication

Power Requirements
Standard unit: 85-265V AC or 90-265V DC
Optional: 12-24V AC or 12-36V DC

Operating Temperature: 0 to 65°C

Approvals: CE marked, UL, cUL listed

DC Process and Temperature Inputs

The APM765 Panel Meter is factory calibrated to accept 4-20 mA, ±10 VDC, Type J, K, T, E thermocouples and 100 ohm platinum RTDs. Process inputs can be scaled with or without applying an input for virtually any engineering units. Temperature inputs can be programmed to display in degrees Fahrenheit or Celsius and a type K thermocouple can display up to 2300°F.

Current/Voltage Input
Setting up the panel meter to accept a current or voltage input is very easy. All setup steps are performed by push-buttons or through software so there are no switches or jumpers to adjust.

Thermocouple/RTD Input
Setting up the APM765 Panel Meter to accept thermocouple or RTD input is simply a matter of setting a switch at the rear of the case and selecting the input type from the menu.
Meters accept J, K, T, or E type thermocouples as well as two, three, or four-wire 100 ohm platinum RTDs.

Serial or Modbus Output
The APM765 Panel Meter can be used as a data acquisition device, with the added benefit of a digital display, by connecting an optional RS-232 or RS-422/485 serial communication adapter.
Acromag offers MeterView software for simple data acquisition and to program the meter.
