Assembly of solid
state relays in bridge connection for switching floating load. The load is
on (terminal A is positive and terminal B is negative) when the power supply
of 12 VDC (LPS12(S)) or 24 VDC (LPS24(S)) is connected. The polarity of the
load is changed by control voltage
(12/24 VDC). There are 4 pieces of SLO 12CRX or SLO 24CRX soldered on the
board. Load rating is 10 A/32 VDC. Note derating
of current for the relays above 30 癈. Check
current switching capacity of the relays. High inductances allowed.
Non overlapping when switched over (break before make).
For DC motors and other applications.
DIN rail mounting (S-version) or srew mounting (without S).
| LPS24L |
Polarity switch, level controlled |
| LPS24LS |
Polarity switch, level controlled
DIN-rail mounting |
Works same as above type, but when only the power is on, all the relays are
in off-state.
The load polarity depends on the level of the control signal:
|
0...2 VDC
|
off-state
|
| 9...15 VDC
|
positive or
clockwise run
|
| 20...32 VDC
|
negative or reverse
