Emerson KJ4006X1-BS1 Redundant AI 8-Channel Terminal Block

The KJ4006X1-BS1 delivers dependable analog input termination for redundant DeltaV control architectures. This terminal block routes eight input channels while supporting dual-redundant field wiring paths. Engineers select this module for its secure screw connections and simple DIN rail installation.

Channel Interface and Input Ratings

The KJ4006X1-BS1 offers eight analog input channels for 4–20 mA field transmitters. Each channel supports redundant wiring paths that maintain signal continuity during controller failover. Furthermore, the terminal block accepts wire sizes from 0.5 mm² to 2.5 mm². It operates across a temperature range of -20°C to 60°C.

Physical Dimensions and Component Count

This terminal block measures approximately 150 mm in length, 90 mm in width, and 45 mm in depth. The unit weighs about 0.40 kg, so technicians mount it securely on standard DIN rail. The assembly includes eight input channels, sixteen terminal points, and two mounting brackets. In addition, labeled identification strips support fast channel tracing during maintenance.

Energy Storage Characteristics

The KJ4006X1-BS1 holds no internal battery or capacitor because it operates as a passive termination interface. Therefore, the module generates no heat and needs no periodic service. This passive design also removes energy storage failure from the maintenance checklist.
