Terminal block and system compatibility

1. Terminal block type and adaptation

Terminal blocks are divided into standard terminal blocks, fuse terminal blocks, redundant terminal blocks, and Mass terminal blocks. Different I/O modules require dedicated terminal blocks, and the core adaptation relationship is as follows:

Example features of terminal block type adaptation module

8-channel standard terminal block, 8-channel AI/AO, 8-channel DI/DO basic wiring, supporting single-mode installation

8-channel fuse terminal block. All 8-channel modules are equipped with 2A fuses to protect the on-site circuit

Redundant 8-channel terminal block with 8-channel redundant AI/AO and DI/DO supports parallel installation of 2 modules to achieve redundant backup

Mass terminal block (16/24/40/48 pins) Plus series modules, some standard modules are compatible with S-series Mass connection solutions or third-party devices (such as Pepperl+Fuchs HiC safety barriers), optimizing on-site wiring

2. System compatibility requirements

Controller: SQ or SX series controllers are required, and V11.3.1 and above versions of the DeltaV system support S-series and M-series controllers running on the same network.

Software version: The Plus series modules (16 channel AI/AO, 32 channel DI/DO) require DeltaV v13.3 or higher.

Installation restrictions: only supports horizontal carriers, not compatible with vertical carriers; Vertical I/O applications require the use of CHARMS electronic grouping I/O.

Certification and Security Standards

International certification:

Electrical safety: CE (EN 61326-1), FM (3600/3611), CSA (C22.2 No.213/1010-1).

Explosion proof certification: ATEX（II 3G Ex ec IIC T4 Gc）、IECEx（II 3G Ex ec IIC T4 Gc）、FM/CSA Class I, Division 2（Groups A-D, T4）。

Classification certification: IACS E10, ABS design evaluation certificate, DNV marine certificate.

Safety design:

Isolation protection: All module channels are optically isolated from the system (1000~1500V DC), and some discrete module channels are additionally isolated from each other.

Fault alarm: Hardware faults (such as module failure, communication interruption, on-site wiring failure) automatically trigger system alarms, with logs recorded in the Event Chronicle, and support for real-time viewing of module status on the diagnostic interface.
