SHIMADEN temperature control instrument SR93-8I-N-90-100R SR93-8P 8Y 8V temperature controller

**Product Overview**

The SHIMADEN SR93 series represents a line of high-performance, microprocessor-based digital indicating controllers designed for precise temperature regulation. The models SR93-8I, SR93-8P, SR93-8Y, and SR93-8V are compact, single-loop controllers featuring advanced control algorithms and versatile input/output configurations to suit a wide range of industrial heating and cooling applications.

**Key Technical Parameters**

*   **Display:** High-brightness, 4-digit, 7-segment LED display (red). Shows Process Value (PV) and Set Point (SV) with a resolution of 1 or 0.1°C/°F.

*   **Input Types:** Universal input supporting thermocouples (Types K, J, R, S, B, E, T, N, W, PLII), RTDs (Pt100, JPt100), DC voltage (0-5V, 1-5V), and DC current (0-20mA, 4-20mA). The specific model suffix (e.g., 8I, 8P) denotes the standard input type supplied.

*   **Control Output:** Options include:

    *   Relay contact output (SR93-8I).

    *   Voltage pulse output for driving SSRs (SR93-8P).

    *   Current output (4-20mA DC) (SR93-8Y).

    *   Position-proportional output for motorized actuators (SR93-8V).

*   **Control Action:** Selectable heating (reverse action) or cooling (direct action).

*   **Control Algorithm:** Advanced PID control with auto-tuning (AT) function. Manual tuning parameters (P, I, D) are also adjustable.

*   **Alarm Outputs:** Typically, one or two independent alarm relays (configurable as upper/lower limit, deviation, etc.).

*   **Power Supply:** 100-240V AC, 50/60Hz (common). The suffix "-90-100R" indicates specific regional voltage variants.

*   **Accuracy:** ±0.3% of span ±1 digit (for standard temperature ranges).

*   **Sampling Cycle:** 200ms.

*   **Ambient Operating Conditions:** 0 to 50°C, 35 to 85% RH (non-condensing).

*   **Panel Cutout:** 45.5
