Terminal block type isolated signal conditioner

The terminal block measures 24.5 (W) × 94 (H) × 40 (D) mm that is compliant with JIS standard circuit breaker dimensions (for single pole). This ultra-compact design helps standardize the design of a control panel and makes DIN rail mounting easier. The module supports wide-range AC power input and provides isolated dual output.


Conformal coating applied as standard

Coating is not only resistant to accidental exposure to corrosive gas or oily smoke, but has a number of benefits contributing to long-term reliability. It avoids direct exposure to air to protect printed circuit boards and electronic parts against humidity, moisture, dust, chemicals, and thermal stress, thereby preventing corrosion, migration and any other damages. (HumiSeal® 1A27NSLU is used as a conformal coating. )


Drop-proof screws employed

The screws employed eliminate the need to care about dropping them during the wiring work. The use of M3.5 screws makes field wiring much easier.


Ceramic capacitors employed

The MS3000 Series employs ceramic capacitors to achieve low current draw with extremely low heat generation, thus leading to long service life.
(The ceramic capacitors are not affected by prolonged use, as opposed to aluminum electrolytic capacitors.)*2


Multi-turn trimmers employed

This series employs multi-turn trimmers for zero and span adjustments. Our conventional series have used 3-turn or 4-turn trimmers, but the multi-turn trimmers employed facilitate fine adjustment and provide improved resistance to vibration. The new trimmers also have static protection.。


Close mounting

The MS3100 Series design is such that the width of the socket is 2 mm (1 mm each side) larger than that of the main unit. Even if you mount two or more sockets side by side, there should always be a clearance between the modules, thereby preventing a rise in temperature around them.


I/O and power terminal covers provided as standard

For safety reasons, the module is provided with I/O and power terminal covers as standard.

DC powered: No aluminum electrolytic capacitors or tantalum capacitors used.
AC powered: Aluminum electrolytic capacitors are partly used in the power section.
