TC-ODJ161 Honeywell 16-Point Isolated Discrete Output Module 24 VDC

Honeywell TC-ODJ161 Isolated Discrete Output Module

The TC-ODJ161 is a 16-point isolated discrete output module for Honeywell control systems. Each point switches independently. Output range covers 10 to 30 VDC. Per-point current reaches 2.0 A at 30 C and 1.0 A at 60 C. Module total reaches 8.0 A at 30 C and 4.0 A at 60 C. Output-to-backplane isolation is 1500 VAC RMS. Response is 1.0 ms OFF to ON and 2.0 ms ON to OFF. The module pairs with the TC-TBCH 36-position terminal block. It suits mixed loads that need point-level isolation.

Oiltech Controls Insight

• Point-level isolation removes cross-channel faults in mixed signal panels.
• The 1500 VAC backplane barrier protects the controller from field transients.
• Per-point 2.0 A rating drives contactors and solenoids without interposing relays.
• Derate to 1.0 A per point when cabinet temperature reaches 60 C.
• Surge handling of 4 A for 10 ms absorbs typical inductive inrush.
• The TC-TBCH 36-position block speeds field wiring and rework.

Oiltech Controls Review

• Engineers value the true channel-to-channel isolation on this module.
• Thermal derating curves match real cabinet conditions, not lab data.
• Response times of 1.0 ms and 2.0 ms fit most discrete interlock loops.
• The isolated design reduces nuisance trips from ground loops.
• It is a practical drop-in for aging Honeywell discrete output cards.

Compatible Equipment

• Honeywell TC series racks with backplane output slots.
• Systems using the TC-TBCH 36-position terminal block.
• Panels driving relays, contactors, solenoids and pilot lamps.
• Mixed-load cabinets that need point-level isolation.
• Legacy Honeywell installations needing spare output capacity.

Professional FAQ

• Q: Can I mix 24 VDC solenoids and 10 VDC signal loads on one TC-ODJ161?
  A: Yes. Each point is isolated, so loads at different voltages within 10 to 30 VDC work together. Check total module current at your cabinet temperature.
• Q: What should I check first when a point will not turn off?
  A: Measure off-state leakage at the field terminal. A reading above 0.5 mA points to a leaky output or a shared return path.
• Q: How do I size the load at 60 C cabinet temperature?
  A: Limit each point to 1.0 A and the module to 4.0 A. Above these values, add interposing relays or improve airflow.
• Q: Is the TC-TBCH terminal block included?
  A: The block is ordered separately in most cases. Confirm your order details with our team before purchase.
• Q: How do I choose between TC-ODJ161 and a non-isolated output card?
  A: Pick the isolated TC-ODJ161 when field wiring shares returns or runs near noise sources. Choose non-isolated cards only for clean, common-return panels.
