About 1762-OW8
The 1762-OW8 is an expansion module used with MicroLogix 1100, MicroLogix 1200 and MicroLogix 1400 controllers. This relay output module is a Programmable Logic Controller (PLC) component relay that is primarily used to enhance the functionality of a specific controller. This output module has Two (2) output groups which serve as isolation, which enable each channel to operate at different voltage range such as 5-125VDC and 5-265VAC. A relay output module is one of the common modules used to automate a process or machine. It is specifically selected when the process has a mixture of instruments or electrical loads that operate in different voltages with high current rating. Sourcing and sinking output modules, particularly MOSFET output modules typically operates at 24VDC with low current capacity. Similarly, a Triac output module has a low current capacity with voltage output of 120/240VAC. Relay output module offers a distinct advantage of being capable of actuating AC and DC loads as the output channels are dry contact outputs with high-current capacity. The module has Two (2) Channel groups, Channel 0-3 forming Group 1 while channels 4-7 forms output group 2. Each channel has a continuous Current rating of 2.0A if operated with 24VDC, 1.0A at 125VDC operation and 2.5A at 120/240VAC operation. It is recommended to install external protection devices such as surge suppressors across an inductive load. The surge suppressor helps protect and maximize the relay contact operating lifespan. Surge suppressor protect the module and individual channels from high inrush current caused by OFF to ON transitions especially with inductive loads. The 1762-OW8Õs Continuous Current per common is 8A and Continuous Current per module 16A with a Total controlled load of 1440 VA. These output bits are writeable bits which changes from 0 to 1 value to represent the state of the field instrument connected to the particular channel. It may also be modified by forcing the bit ON/OFF. Forcing action is typically used during testing and commissioning phase and sometimes used by plant personnel to simulate, test or permanently activate a load however, forcing is not recommended to be left activated unless it is necessary to do so. This 1762-OW8 is an electronic device, sensitive to electrostatic discharge. When handling this module, electrostatic charges must be prevented from entering the module. This can be done by not touching the electronic components of the module, touching a grounded object for a short period to discharge a personÕs electrostatic charge, wearing a wrist-strap that is connected to ground. When temporary placing the module to a flat surface, ensure that the surface is grounded.F.A.Q for 1762-OW8
| Q: 1. Can this module be used to replace the 1762-OW16? | A: Yes, however, if the 1762-OW16 is occupied up to the 9th channel, Two (2) 1762-OW8 is required. If less than 8 channels are utilized, the 1762-OW8 may be used as a replacement. In any instance, hardware reconfiguration is required. |
|---|---|
| Q: 2. How many 1762-OW8 may be installed with each MicroLogix controllers? | A: MicroLogix 1100 supports up to 4 expansion modules, 6 with MicroLogix 1200 and 7 with MicroLogix 1400. |
| Q: 3. What is the mechanical rating of the contact outputs? | A: The moduleÕs minimum contact rating is x 10_ operations @ 3A 30V DC or 250V AC, Resistive. |
PDFsupply Tech
The 1762-OW8 is an 8-channel relay output module. This module features the same advantage as the 1762-OW16, compatible with a variety of Voltage range particularly 5-125VDC and 5-265 VAC. However, this module has lesser output channels, with only 8 channels compared to the 1762-Ow16 which has 16. This module main advantage is with the cost-effectivity as it cost much lesser compared to the 1762-OW16.
