OPTO 22 SNAP-AOVA-8 控制模块
OPTO 22 SNAP-AOVA-8 ANALOGUE OUTPUT MODULE, 8-CH
OPTO 22
The SNAP-AOVA-8 is an Analog Output Module has 8 channels, each individually configurable for any one of six voltage or current output ranges. Requires a 24VDC excitation voltage brought in through the field connector on the top of the module. This voltage is internally isolated with transformer and digital data isolators and then used to source all channels. Because all current is sourced from within the module using the 24VDC excitation, current outputs cannot be used with an external loop supply. Current outputs are self-sourcing and cannot be used in loops that are loop-powered or already have a self-sourcing device in the loop. It mounts on a SNAP PAC rack alongside other I/O modules (digital, analog and serial). This module requires a SNAP PAC brain or rack-mounted controller with firmware version R9.4b or higher. It cannot be used with legacy controllers or brains. To wire the module, a 6-foot-long SNAP-HD-20F6 cable is required. 1500V Transient isolation 15ms Nominal 24V excitation fault recovery time 9ms Nominal (update 1-channel/ms) data refresh time 22 to 14AWG Wire range Current Rating: 20mA Product Range: - SVHC: No SVHC (17-Dec-2015) Find similar products grouped by common attribute
