功能

• Trip settings are set by links on the board in this unit. Four units, including a signal isolator/converter, insulate the signal with an optical isolation hybrid circuit. The 0-10 V dc/4-20 mA and 4-20 mA/0-10 V dc units convert the process signal to the specified standard transmission voltage or current signal.
• Signal Conditioning Unit
• RS Pro single or dual trip amplifiers provide a function to configure each trip so that the alarm condition can be set above (high trip) or below (low trip) the set point. This relay can be switched from energized to de-energized (failsafe) or switched from de-energized to energized (non-failsafe) under alarm conditions.
• Dual Supply Voltage Operation 2-Color LED Status Display Adjust the "Trip Level" on the front panel
• Achieves 3-port insulation by supplying power to the input and output stages from the independent secondary side of the power transformer LED display for dual supply voltage operation "Power On"
