Product Description:
The M.1016.2568 is a signal cable assembly manufactured by Danaher for the Block IO Analog Modules series. It is designed to carry differential process variables between field instrumentation and the associated analog slice inside a control cabinet. The assembly’s pre-assigned pin map eliminates individual point-to-point terminations, reducing wiring complexity and the chance of connection errors. Within distributed control enclosures, it functions as the fixed interface between analog devices and the series node, maintaining characteristic impedance and supporting clear channel identification during service. It supports orderly cabinet layouts where multiple analog loops are grouped within a compact node assembly.
The harness employs a Twisted Pair topology to minimize electromagnetic interference on low-level voltage or current loops. Inside the jacket sit 4 insulated conductors, providing separate paths for transmit, receive, and reference circuits. Each conductor is sized at 24 AWG, giving adequate copper cross-section without sacrificing bend radius in tight cable ducts. Connection to the I/O slice occurs through a 9-Pin Male D-Sub, whose metal shell provides strain relief and proper mating orientation. To further suppress crosstalk, every signal pair is Individually Shielded, so common-mode noise from nearby motor drives is diverted to ground before reaching sensitive input amplifiers. The compact cable layout also supports neat routing alongside other low-level control wiring inside the enclosure.
Ground continuity for the shield can be landed on Pin 7 or connector shell, accommodating different plant grounding schemes. The receive channel enters the module on pins 5 and 6, identified by the color code Red and Black and marked "In" on the housing. The transmit path exits on pins 3 and 4 and is labeled "Out," while unused pins 1, 2, 8, and 9 remain isolated to help prevent accidental shorts when test equipment is connected. This separation of channel directions and color coding keeps signal paths easy to follow during loop checks and routine cabinet work. The arrangement also reduces ambiguity when verifying channel direction after installation or during later modifications.
