heating off , switching of fans. µFunction Features-Single-function relay with possibility of time setting by a potentiometer.-Choice of 2 functions: A:Delay ON B:Delay OFF-Time scale 0.1 s - 10 days divided into 10 ranges. - Relay status is indicated by LED. - 1-MODULE,DIN rail mounting. Technical parameters GRT8 A1 B1-/ GRT8 A2 B2 ...
Function C : Off-Delay Relay with Control Signal Description After power-up and closing of the control contact C, the output R closes. When control contact C re-opens, timing T starts. At the end of the timing period, the output(s) R revert(s) to its/their initial state. The second output can be either timed or instantaneous. Function: 1 Output
The CT-ARE is an electronic time relay with OFF-delay. It is from the CT-E range. The CT-E range is the economic range of ABB‘s time relays and offers a cost effective price-performance ratio for OEM users. This is achieved by simplified functionality and results in the simplest of setup procedures. The CT-E range
• OFF delay timers are with aux. voltage (refer wiring diagram fig.1). Same potential must be applied to A1 and B1, or A3 and B3. • With the two-voltage version, only one voltage range must be connected. • The activation of loads parallel to the start input is not permissible when using AC control voltage (see diagram below). Mounting
The Bulletin 700–FS Electronic High Performance Timing Relays consist of Multi–Function, Single Function and Special Function designs. These products offer the customer optimum space utilization and maximum functionality. In addition, the timing ranges are easily adjusted, and the LEDs provide visual indication of the coil and timing status.
