Number
CZ2H-IDC2 Solid State Contactor, 2 channels
at up to 100 amps per channel, 480V max, DC control input. Includes heat
sink.
DIN RAIL CLIP Clips onto a standard 35 mm din rail
CZ-JUMPER Convert from dual pulsing inputs to
one 0-10 VDC analog input.
CZ-INPUT
RESISTOR Convert from a 4-20mA signal from a temperature
controller or PLC. 1) Change controller to a 0-20mA, 2) then add this resistor
at the controller, across the 0-20mA terminals. This is a 499 ohm, 0.1%, 0.5
watt resistor such as a DigiKey RNF12BTE499RCT-ND
CZ2H-IDC2-A02 Solid State Contactor "Top Hat"
assembly. This is the electronic section of the CZ2H product ONLY. Customer
to supply own heat sink. Example: for replacement purposes, for large
applications (100-500 zones) using a large external heat sink, or military
applications when installed directly to the ship or vehicle's frame. Always use
Thermal Transfer Compound
(Thermal Grease) when installing a "A02" Top Hat assembly onto a heat
sink.

input and ALERT wiring. For high amperage inrush applications (motor
starters, municipal lighting, stadium lighting, etc.) confirm that the maximum
amperage requirements for the load is less than 180 amps for 2 seconds.

0-10VDC analog
input |
By
inserting a jumper, the CZ2H-IDC2 will now accept a 0-10 VDC analog control
input and convert that information to ON/OFF/ON/OFF outputs on both channels.
The outputs will be based upon a 1 second total cycle time (for many resistive
loads) OR will be based upon half cycles (for fast responding loads, IR lamp
loads, etc). |
Diagnostics
output |
The
ALERT output will activate upon: SCR #1 failed open or closed, SCR #2 failed
open or closed, SCR incapable of switching (OK now, but can not switch when
commanded), no incoming power (open fuse), no outbound power (open load), and
thermal shutdown. The "incapable of switching ALERT" is a Power-io exclusive
feature. For example: a dropped tool momentarily shorts the load during a
machine change-over. The machine starts OK and the loads are ON during start
up. The ALERT activates because the SCR is damaged and is incapable of future
switching as requested. The standard
diagnostics range is for a line voltage of 100 - 480 VAC. Contact Power-io for
diagnostics outside this voltage range. |

I²T fuse greater than 100 amps. |
