1771-OYL

The Allen-Bradley 1771-OYL is a PLC-5 digital dry-reed relay contact output module. It has 8 output points available, 4 of which are N.O. (normally open) or Form A and 4 are N.C. (normally closed) or Form B. These output points are grouped into 4 sets with 2 outputs in each set. It also has 8 status indicators corresponding to each output. When an output relay is energized, its corresponding status indicator will be lit up. The 1771-OYL module can be installed in a 1771 Series A or B I/O chassis and uses a 1771-WD field wiring arm. This module has voltage ratings of 0-24V AC RMS and 0-24V DC. The 1771-OYL has a maximum current rating of 100 mA per output and the module's surges, peaks, and spikes must fall within its power rating. At the module's rated power, it has a maximum surge current of 100 mA per output. This module has a DC power rating of 2.4 W per output and a suppressed AC power rating of 2.4 W, both of which are resistive. Its minimum contact loads are 10 mA at 24V each for both DC and AC. Maximum backplane current of this module is 420 mA and isolation voltages are 1000V for open contacts and 1500V for the coil to the contacts. The signal delay of this module is 1 ms for both on and off. The 1771-OYL also has a 1 ms maximum operate/release time, as well as bounce time. Its maximum switching frequency is 10 Hz. The power dissipation is a minimum of 2 W and a maximum of 2.2 W, while the thermal dissipation ranges from a minimum of 6.9 BTU/hr to a maximum of 7.6 BTU/hr. This module has an operating temperature of 0-60 ??
