Fastron FRT8-M2/W240, Multifunction Timer 12-240 V AC/DC, 0.1s - 10 Days, 2 x SPDT 16 Amp C/O Contacts Replaces Elko CRM-91H,CRM-93H,CRM-9S
Features :
Multi-range (0.1s - 10days)
Multi-voltage 12 →240 V AC/DC
LED status indicator
Possibility of external load connection in parallel to the control input
Suitable replacement to Elko CRM-91H,CRM-93H,CRM-9S
Multifunction Timers Includes The Following :
A: A pulse after power-on or after the rising edge of trigger pulse S.
B: Delay after power-on or after the rising edge of trigger pulse S.
C: A pulse after power-on or after the rising edge of trigger pulse S. Retriggerable.
D: Delay after power-on or after the rising edge of trigger pulse S. Retriggerable.
E: The first edge of trigger pulse S turns relay on while the second edge starts counting down till relay off. Additional trigger S before the process is finished prolongs the on-state.
F: Each rising edge of trigger S appends additional period T to the time of on-state.
G: Pulsating operating with a starting pulse or pause which depends on the state of trigger S at power-on.
H: Bistable operating. Each rising edge of trigger S swaps the relay into the opposite state.
I: Prolonged pulse after power-on. The presence of trigger S temporarily stops counting.
J: Prolonged pause after power-on. The presence of trigger S temporarily stops counting.
