Datasheet
**Data sheet** ## Electronic timer CT-ERD.22 ON-delayed with 2 c/o (SPDT) contacts The CT-ERD.22 is an electronic time relay with ON-delay. It is from the CT-D range. With their MDRC profile and a width of only 17.5 mm, the CT-D range timers are ideally suited for installation in distribution panels as well as for industrial applications where compact dimensions are required. **==> picture [182 x 57] intentionally omitted <==** **----- Start of picture text -----**<br> |s<br>@<br>2CDC 251 091 F0006<br>**----- End of picture text -----**<br> ## Characteristics - Rated control supply voltage 24-48 V DC, 24-240 V AC - Single-function timer ON-delay - 7 time ranges (0.05 s - 100 h) in one device - Light-grey enclosure in RAL 7035 - 2 c/o (SPDT) contacts (250 V / 5 A) ## Approvals A UL 508, CAN/CSA C22.2 No.14 R EAC E CCC L RMRS - Width of only 17.5 mm (0.689 in) - 2 LEDs for the indication of operational states ## Marks a CE b RCM ## Order data |Order data||||| |---|---|---|---|---| |Type|Rated control supply voltage|Time range|Output|Order code| |CT-ERD.22|24-48 V DC, 24-240 V AC|0.05 s - 100 h|2 c/o (SPDT) contacts|1SVR 500 100 R0100| Functions ## Operating controls 1 Rotary switch for the preselection of the time range - " 2 Potentiometer with direct reading scale for the fine adjustment of the time delay - 3 Indication of operational states - U: green LED - V control supply voltage applied W timing R: yellow LED - V output relays energized **==> picture [219 x 137] intentionally omitted <==** **----- Start of picture text -----**<br> Ss Airy sfge A2 4<br>BO, os Hae<br>& ~ 31<br>40h '- le<br>aa 100m,wa<br>ae |<br>* 2<br>2CDC 251 091 F0006<br>**----- End of picture text -----**<br> - " 4 Circuit diagram ## Application With their structural form and their width of only 17.5 mm, the CT-D range timers are ideally suited for installation in distribution panels. ## Operating mode The CT-ERD.22 has 2 c/o (SPDT) contacts and offers 7 time ranges, from 0.05 s to 100 h. The time delay range is rotary switch selectable on the front of the unit. The fine adjustment of the time delay is made via an internal potentiometer, with a direct reading scale, on the front of the unit. 2 - Electronic timer CT-ERD.22 | Data sheet Function descriptions / diagrams ## A ON-delay This function requires continuous control supply voltage for timing. Timing begins when control supply voltage is applied. The green LED flashes during timing. When the selected time delay is complete, the output relays energize and the flashing green LED turns steady. If control supply voltage is interrupted, the output relays de-energize and the time delay is reset. **==> picture [391 x 103] intentionally omitted <==** **----- Start of picture text -----**<br> A1-A2<br>15-18, 25-28<br>15-16, 25-26<br>green LED<br>t < t<br>t = adjusted time delay<br>2CDC 252 106 F0206<br>**----- End of picture text -----**<br> ## Electrical connection **==> picture [511 x 147] intentionally omitted <==** **----- Start of picture text -----**<br> A1-A2 Rated control supply voltage Us 24-48 V DC or 24-240 V AC<br>A1 15 25 15-16/18 1st c/o (SPDT) contact<br>25-26/28 2nd c/o (SPDT) contact<br>A1 15 25<br>A2 16 18 26 28<br>18 16<br>28 26 A2<br>2CDC 252 115 F0b06<br>**----- End of picture text -----**<br> Connection diagram Data sheet | Electronic timer CT-ERD.22 - 3 ## Technical data Data at Ta = 25 °C and rated values, unless otherwise indicated ## Input circuits **==> picture [511 x 258] intentionally omitted <==** **----- Start of picture text -----**<br> Supply circuit A1-A2<br>Rated control supply voltage Us 24-240 V AC, 24-48 V DC<br>Rated control supply voltage Us tolerance -15...+10 %<br>Typical current / power consumption 24 V DC 21 mA / 0.5 W<br>115 V AC 20 mA / 1.2 VA<br>230 V AC 31mA / 1.9 VA<br>Rated frequency DC;
