Product Details
The AB 1771-OFE1 is a PLC 5 analog output module. It is a voltage
version which converts 12-bit binary or 4-digit BCD (binary-coded
decimal) values to analog signals using its 4 outputs. It has three
selectable voltage ranges of 1 – 5V DC, 0 – 10V DC, and ±10V DC.
Peripheral devices such as motor speed controllers, valve
positioners, recorders, or signal converters can be connected to
the output. The 1771-OFE1 uses block transfer programming for data
transfer. Write Block Transfer instructions move data up to 13
words away from the processor to the module for DA conversion in
one scan and Read Block Transfer moves 5 words of data from the
module to the processor as part of the debugging process.
The 1771-OFE1 module has 4 1000V individually-isolated differential
outputs. It requires a power of 1.4A at 5V which is supplied from
the I/O chassis backplane thus no external power supply is needed.
It has a channel update time of 8ms per 4 channels for BCD and
1.6ms per 4 channels for Natural Binary. It has a maximum power
dissipation of 7.9W and maximum thermal dissipation of 26.9 BTU/hr.
The 1771-OFE1 includes a wiring arm to replace the module without
disconnecting the wires. It can be installed in any slot in a 1771
I/O chassis and keying bands must be snapped between 10-12 and
26-28 for fixing that slot.
The 1771-OFE1 module can convert raw data to engineering and
measurement units such as °C, °F, gallons/minute, and pounds/square
inch. For diagnostics, it performs a self-check at start-up. If a
fault occurs, a red fault indicator LED and the green power status
indicator LED remains OFF. The 1771-OFE1 has a 1500V optoelectrical
isolation and this protects the system from overvoltage situation.
