Card Rack Module

The DigiTrace Card Rack Module controls up to 5 heat-tracing circuits. The Card Rack Modules are available in two versions, the DigiTrace NGC-30 CRM (for mechanical relays) and the DigiTrace NGC-30 CRMS (for solid state relays). Up to four of these Card Rack Modules can be installed in a panel mounted Card Rack. RTD’s are either directly connected to the DigiTrace CRM(S) or alternatively collected via RMM’s locally or centralized in the field (distributed architecture). The CRM/CRMS solution can control up to 260 individual heat-tracing circuits and monitor up to 388 temperature inputs (including 128 temperature inputs via RMMs).
