Watlow ANAFAZE PPC-TB50 (Part Number 30280-00) 50-pin SCSI Terminal Adapter Board
I. Basic Information
Brand: Watlow (Wattron) ANAFaze PPC-2000 Series Compatible Terminal Base
Material Code: 30280-00 = PPC-TB50
Position: I/O Signal Wiring Terminal Board, not a temperature control host, but a field wiring transfer module for the processor/CLS multi-loop controller
Model Explanation
PPC: PPC-2000 Programmable Process Control Platform
TB50: Terminal Block 50 for SCSI Interface Terminal Block
30280-00: Original Factory Part Number
II. Hardware Structure and Interfaces
Connection Port
Standard 50-pin SCSI Male Connector, connected to PPC-2010 Main Control CPU and CLS208 Multi-Loop Temperature Control Card via dedicated 50-core shielded cable
Field Wiring Port
4 groups of green spring screw terminal blocks, totaling 48 digital DI/DO points; wire diameter compatible with 14-22AWG (0.35-2.0mm²), tightening torque 0.5-0.6N·m
Expansion Compatibility
Can connect pulse encoder signals
Support external SDAC Analog Input Module (temperature, pressure 4-20mA / thermocouple / RTD)
One pulse input reserved, suitable for speed and positioning acquisition
Electrical and Installation Specifications
Power Supply
Terminal Board Passive, powered by the main control module through SCSI cable 24VDC circuit Installation method
DIN35 standard rail snap-in installation
Also supports screw wall-mounted fixation
Environmental conditions
Operating temperature: -40℃ ~ +85℃; humidity 5%–95% without condensation; industrial EMC anti-interference; CE safety certification
Size standard for industrial control small boards, lightweight and saves cabinet space
IV. Core functions and roles
Signal separation protection
Isolate the precise SCSI interface of the main control board from the strong interference wiring on site, protecting the pins of the motherboard from being pulled, short-circuited or burned
Simplified wiring
Short SCSI lines connect to the motherboard inside the cabinet, and the external thick cables are directly crimped to the terminals, making construction, maintenance and line replacement more convenient
Full I/O conversion
Digital input: limit switches, temperature switches, fault relay points, equipment status feedback
Digital output: drive SSR solid-state relays, solenoid valves, alarm indicator lights, contactor coils
System expansion bridge
One PPC-TB50 with one PPC-2010 processor; in a multi-card system, multiple TB50s can be respectively connected to different CLS temperature control sub-cards
