Parameter Specification Product Family / System ABB Freelance Distributed Control System (DCS) Module Type Digital Input Module Article Number CEPY1-2001 Number of Channels 16 (Sixteen independent input channels) Input Type Sinking or Sourcing (typically configurable, for connection to PNP or NPN sensors). Designed for 24V DC field devices. Nominal Input Voltage 24 V DC Permissible Input Voltage Range Typically 19.2 V DC to 30 V DC Input Current per Channel Typically 3-5 mA (at 24V DC) Logic "1" Signal Level ≥ 15 V DC (ON state) Logic "0" Signal Level ≤ 5 V DC (OFF state) Isolation Channel-to-Channel Isolation: Typically not isolated. Group Isolation: Channels are isolated from the system bus/power supply (e.g., 500 V AC). Connection Method Via a removable front connector block (e.g., screw terminal or spring-cage type), which connects to the module's rear connector. Common wiring for field devices. Diagnostics Module status indication via LEDs (e.g., POWER, READY, CHANNEL STATUS). May support wire-break detection. Mounting DIN rail mounting (35 mm) within a Freelance 800F I/O station enclosure or panel. Bus Communication Connects to the Freelance Controller (AC 700F/900F) via a local I/O bus (e.g., CI830 or CI840 communication interface module and associated bus). Ambient Temperature Operation: 0°C to +60°C (standard) Storage: -40°C to +85°C Standards Compliance IEC 61131-2, cULus Listed, CE Marked, etc.
