Warranty: 365 days
Delivery: 1 week for in-stock; no more than one month at the latest
Payment: 50% advance payment; full payment before delivery
Express options: FedEx, UPS, DHL
24 VDC discrete outputs: Suitable for driving solenoids, relays, and indicator devices in most process environments.
Multi?channel density: Typically 16 outputs per module, helping reduce cabinet footprint and cost per point.
Sourcing-type outputs: High?side switching that plays nicely with common industrial wiring practices.
Electronic protection: Overload/short?circuit protection and per?channel status for quick fault isolation.
DeltaV-native integration: Seamless recognition on the DeltaV backplane; channel forcing and simulation support are commonly available for testing.
Group isolation: Channels are usually arranged in groups, allowing practical field power segregation.
Compact installation: Fits standard DeltaV M?series I/O carriers with removable field terminal blocks for tidy wiring.
| Brand / Model | Emerson DeltaV / KJ2231X1-EB1 (Digital Output Module) |
| HS Code | 853890 (Parts for electrical control/switching apparatus) |
| Power Requirements | Backplane powered via DeltaV M?series I/O carrier; field supply 24 VDC nominal for loads |
| Outputs (Type / Density) | Discrete 24 VDC, sourcing (high?side), typically 16 channels; per?channel protection and status |
| Per?Channel Load Rating | Up to 0.5 A per channel (typical for DeltaV DO modules; verify against load requirements) |
| Operating Voltage (Field) | 24 VDC nominal (commonly acceptable range 18–30 VDC) |
| Communication Interfaces | DeltaV backplane interface to controller; no external comm ports on the module |
| Installation Method | Installs in DeltaV M?series I/O carrier (DIN rail); field wiring via removable terminal block |
| Operating Temperature | 0 to 60 °C (32 to 140 °F) typical |
| Dimensions & Weight | Standard M?series I/O module footprint; approx. 0.25 kg |
This module shows up most in continuous and batch process control where reliable DO switching is critical:
Oil & Gas: wellpad valve manifolds, separator skids, ESD solenoids
Chemical & Petrochemical: reactor valve packs, purge systems, safety beacons
Water & Wastewater: blower contactors, chemical dosing solenoids, pump starters (via interposing relays)
Power & Utilities: damper actuators, lube oil skids, MCC interfacing
Life Sciences & Food/Beverage: SIP/CIP valves, utility distribution valves, conveyor signaling
“We swapped in KJ2231X1-EB1 cards during a brownfield DeltaV expansion—no fuss on recognition, and channel diagnostics helped us pinpoint two miswired solenoids in minutes.” — Maintenance Lead, midstream gas facility
Reliability that reduces downtime: Protected outputs and clear channel status minimize nuisance trips and speed up recovery.
Seamless compatibility: Native DeltaV behavior means less integration risk and faster commissioning.
Cabinet space efficiency: Higher channel density typically lowers per?point cost and wiring bulk.
Lifecycle support: Firmware and diagnostics that align with standard DeltaV toolsets keep maintenance simple.
Spares strategy: Using the same DO card family across skids or units simplifies inventory and training.
Panel/cabinet: Mount the M?series carrier on DIN rail inside a clean, dry enclosure (IP54 or better is common). Allow adequate ventilation around the I/O stack.
Wiring practices: Use 24 VDC field power sized for the total load. Separate DO wiring from high?noise cables. For inductive loads (solenoids, relays), add diode or RC suppression across the coil to protect outputs.
Grounding: Follow DeltaV grounding and shield termination guidelines to reduce EMI and improve diagnostics accuracy.
Commissioning: Use DeltaV channel force/simulate to verify each output and confirm field device actuation before process startup.
Maintenance: Periodically check terminal tightness and inspect for heat discoloration on high?load channels. Keep firmware aligned with your system baseline during planned outages.
Safety: De?energize and lock out the panel before handling the module or terminal block. Validate ESD protection when working on open carriers.
CE marked; designed for industrial EMC environments
UL/CSA recognized components in most deployments
RoHS compliant in many regions
Manufacturer warranty typically 1 year (our coverage: 365 days)
