FAQ

Q: Does every channel support HART?
A: Yes, all 16 channels are HART-enabled, allowing advanced diagnostics and remote configuration of smart field devices.

Q: What terminal block do I need?
A: Use a rotary-keyed terminal block set to position A2 for proper compatibility.

Q: Can this card be used in harsh environments?
A: Yes, it is rated for −40 °C to +70 °C and meets ISA-S71.04 Class G3 airborne contaminant standards.

Installation Guidelines

1. Set the terminal block key to A2.
2. Install the card into an available S-Series carrier slot.
3. Connect 4–20 mA field wiring with shielded twisted-pair cable.
4. Verify HART device communication via DeltaV Explorer.

Selection Tips

• Choose KJ3223X1-BK1 when you need 16 analog input channels with HART diagnostics.
• Calculate total bussed field power (600 mA max) to ensure all channels can be powered.
• For non-HART applications, a standard AI card may be more cost-effective.
