1771-OZL | Allen-Bradley PLC 5 Digital Contact Output Module, 8 (4 Sets of 2)

Description

The Allen-Bradley 1771-OZL output module is a PLC 5 series output module with dry-reed relays. Dry-reed relays are hermetically sealed relays that can be used in noxious environments. The 1771-OZL output module is suitable for low-power and low-voltage applications because of its dry-reed relays, but it should not be exposed to surge currents which could damage the relays. The 8 outputs in the output module are arranged in 4 groups of 2 outputs each. The 1771-OZL output module operates with voltage ratings of 0 to 24 Volts AC RMS and 0 to 24 Volts DC.

Technical Specifications 

Information About 1771-OZL

The Allen-Bradley 1771-OZL is a PLC-5 digital dry-reed relay contact output module. It comes with an 8 Form A or N.O. (normally open) output points that are grouped into 4 sets of 2 outputs, with each group having its own common. These outputs are electrically-isolated from the module’s logic circuitry. Eight status indicators on the front plate of the module are available representing the control status of the output relays. Once a relay has been energized, its corresponding indicator will be lit up. It uses a 1771-WD wiring arm and can be installed in a 1771 Series A or B I/O chassis. The entire 1771-OZL module measures 4.38 x 1.5 x 11.81 inches. 

The voltage ratings of this module are 0-24V AC and 0-24V DC and maximum current rating is 100 mA per output. Note that the peaks, surges, and spikes must fall within the range of the power rating. The 1771-OZL has power ratings of 2.4 W resistive each per output for both DC and suppressed AC. This module also has minimum contact loads of 10 mA at 24V each for both AC and DC. The isolation voltage is 1000V for open contacts and 1500V for coil-to-contacts and its backplane current is a maximum of 420 mA. 

It has 1 ms maximum bounce time and operate/release time. The 1771-OZL module also has a maximum switching frequency of 10 Hz and a 1 ms signal delay for both on and off states. Its power dissipation ranges from a minimum of 2 W to a maximum of 2.2 W, while thermal dissipation is a minimum of 6.9 BTU/hr and a maximum of 7.6 BTU/hr. The 1771-OZL has a non-condensing relative humidity of 5-95%, an operating temperature that ranges from 0-60
